        459.307  CONSTRUCTION DESIGN STANDARDS -- FORMED      MANURE STORAGE STRUCTURES.         The department shall adopt rules establishing construction design      standards for formed manure storage structures that are part of      confinement feeding operations other than small animal feeding      operations.  However, the construction design standards shall apply      to a formed manure storage structure that is part of a small animal      feeding operation as provided in section 459.310.         1.  The department may provide for different standards based on      criteria developed by the department, which may include any of the      following:         a.  The animal unit capacity of the manure storage structure's      confinement feeding operation or the manure storage structure's      manure volume capacity.         b.  Whether the manure storage structure stores only dry      manure.         c.  Whether the manure storage structure is part of a      confinement feeding operation building.         d.  The use of concrete, including its use for the structure's      footings, walls, or floor.         2.  The construction design standards shall be based, to every      extent possible, on uniform standards such as available standards      promulgated by ASTM (American society for testing and materials)      international.  The department may require that all or any part of a      formed manure storage structure be constructed of concrete.         3.  The construction design standards for concrete shall provide      for all of the following:         a.  The concrete's minimum compressive strength calculated on      a pounds-per-square-inch basis.         b.  The use of reinforcement, including but not limited to the      grade, amount, and location of steel rebar or fiberglass, wire mesh      or fabric, or similar materials set in the concrete, or the use of      exterior braces to support joints.         c.  The depth of footings.         d.  The thickness of the footings, the floor, and walls.         4.  A person shall only construct a formed manure storage      structure on karst terrain or an area which drains into a known      sinkhole pursuant to upgraded construction design standards necessary      to ensure that the structure does not pollute groundwater sources.
